Patent DE-3530464-A1 (DE)
Title: Detergent composition suitable for washing textiles in washing water of a raised temperature of at least 60 DEG C
Inventor: SOMERS ANDREAS JAN
IPC: C11D1/66
Filed: 1985-08-27
Abstract: The softening effect of softening detergents containing non-ionic surfactant and a cationic quaternary ammonium compound as a softener is improved, in particular at raised washing temperatures of at least about 60 DEG C, if a highly ethoxylated non-ionic surfactant having a cloud point temperature above the raised washing temperature is used. The preferred non-ionic surfactants are the C12-C14-fatty alcohols and C8-9-alkylphenols ethoxylated with 15 to 30 mol of ethylene oxide. The cloud point of the composition can be raised by incorporation of an amphoteric surfactant in the composition.

Title: Method for controlling two heat sources acting on a heat exchanger
Inventor: TAAG JUERGEN
IPC: G05D23/20
Filed: 1986-03-01
Abstract: Method for controlling two gas-fired boilers of the same maximum output, which dissipate their heat to a consumer in the form of a plurality of radiators, convectors or floor heating sections connected in parallel or in series, or a service water heater. One boiler is either operating at full load or switched out while the other boiler is clocked in accordance with a mark-to-space ratio. When the desired temperature of the heating system is reached by both boilers in operation, the one operating in accordance with the mark-to-space ratio is immediately shut down, whereas that operating in the pure two-point mode is not shut down until after the expiry of a delay time, when the actual temperature value of the temperature to be controlled is still above the desired temperature value.

Title: Roller punch for punching blanks out of two dimensional, limp material for cutting
Inventor: LEBHERZ HERMANN
IPC: B26F1/42
Filed: 1986-03-12
Abstract: The invention relates to a roller cutter for punching blanks out of two dimensional limp material for cutting. A sandwich-like structure composed of a self-contained flexible cutting plate with material for cutting placed on it and punching tools located on the latter is pulled through the gap between a pair of punching rollers which are driven in a rotary manner. A line of conveying rollers is mounted upstream and downstream of the pair of punching rollers. Upstream and downstream of the upper punching roller there is mounted an auxiliary roller in each case, which can be adjusted in a vertical direction jointly with the upper punching roller. The auxiliary rollers are mounted so as to be inflexible in a vertical direction. In order to impart an upwardly directed bulge to the sandwich-like structure while it passes between the rollers, the two punching rollers, which exert the punching pressure, of the pair of rollers are brought out of adjustment in an upward direction with respect to the line of conveying rollers and/or the two auxiliary rollers. A bulge in the sandwich-like structure of this type while it passes through the rollers counteracts a milling effect, so that cleanly cut and dimensionally accurate blanks can be produced.

Title: Matrix keyboard
Inventor: QUIRDER KLAUS DR ING
IPC: H03M11/00
Filed: 1986-10-02
Abstract: In a matrix keyboard, particularly a membrane keyboard, switching contact points (K11 to K33) with series resistors (R1) are provided where the row lines (Z1, Z2, Z3) and column lines (S1, S2, S3) cross. To avoid phantom voltages at open switching contact points when a plurality of switching contact points are closed, and so that the switching elements necessary for this purpose can be in pressure technology, there is an ohmic shunting resistor (R2) on each column line (S1 to S3). The series resistors (R1) of the closed switching contact points of a column line and of the row lines which are not triggered are parallel to the shunting resistor (R2) of this column line. In series with this parallel circuit is the series resistor (R1) of the closed switching contact points of this column line and of the triggered row line. <IMAGE>
Patent DE-3636146-A1 (DE)
Title: Chlorine-containing resin for mouldings
Inventor: TAKAHASHI MASAMI
IPC: C08K5/17
Filed: 1986-10-24
Abstract: The invention relates to mouldings made from chlorine-containing plastic and materials therefor which are characterised in that they have been stabilised by an amino acid and contain essentially no metal ions. The present materials can contain from 0.5 to 5 parts by weight of amino acid per 100 parts by weight of chlorine-containing plastic, such as PVC. In contrast to chlorine-containing plastics containing a metal-containing stabiliser, there is no possibility of metal ions becoming free in the mouldings and the material of the invention, so that the present mouldings can advantageously be used for the electrical industry and semiconductor industry for medical purposes, chemicals, pharmaceuticals, foodstuffs and other uses where liberation of metal ions can interfere. The invention also relates to nonmetallic colorants and lubricants for mouldings and materials made from chlorine-containing plastics.
Patent DE-3641982-A1 (DE)
Title: Process for producing cavities in refuse dumps
Inventor: HAASE HARRY
IPC: B09B1/00
Filed: 1986-12-05
Abstract: For the purpose of recovering gas from refuse dumps, gas-extraction pipes (4) are inserted in refuse dumps by driving, boring or excavating the required shaft by means of grabs. This process for producing shafts or other caverns is extremely high in outlay and, in view of the extremely inhomogeneous structure of the refuse-dump body (50), extremely arduous. For the simplified production of a shaft, a primary shaft is produced, the cross-sectional dimensions of which are considerably smaller than those of the definitive shaft (30). Explosive is introduced into the primary shaft. The explosion is then carried out, as is thus a displacement of the material delimiting the shaft, that is to say a widening of the narrow shaft to form a considerably enlarged shaft (30) into which the filter pipe (4) can be introduced, whereupon the remaining shaft area is filled with ballast (41). In addition to the substantial saving on large and heavy driving, boring or grab equipment, the invention provides a considerably enlarged shaft-wall surface by adapting the explosive charge to the desired shaft or cavity geometry. <IMAGE>
Patent DE-3701722-A1 (DE)
Title: Internal combustion engine, especially for motor vehicles
Inventor: INDRA FRITZ DR ING
IPC: F02B3/06
Filed: 1987-01-22
Abstract: An internal combustion engine, especially for motor vehicles, with direct fuel injection into the combustion chamber recess of the piston has a deflecting surface for the injected fuel jet extending into the combustion chamber recess, which deflecting surface is formed by a deflector body fixed in the side wall of the combustion chamber recess. The deflector body is of spherically convex design at least on its area forming the deflecting surface and extending into the combustion chamber recess. The said measures prevent the injected fuel jet from directly striking the combustion chamber recess wall and fuel being deposited there which might form soot and excessively reduce the local wall temperature. At the same time, the directed air flow (swirl) produced by the inlet elements is, however, in no way impaired by this. The fuel droplets formed when the injected fuel jet strikes the deflecting surface are reflected by the deflecting surface back into the area of maximum fluid flow, thereby producing optimum vaporisation and mixing of the fuel mixture.
Patent DE-3702844-A1 (DE)
Title: Process and extrusion blow-moulding machine for the production of flat bottles
IPC: B29C49/18
Filed: 1987-01-30
Abstract: A process for the production of flat bottles with a flat or concave base by the free extrusion of a plastic parison provides for the blowing of an intermediate moulding with circular cross-section and the forming of said intermediate moulding essentially mechanically to form the flat bottle with simultaneous finish blow-moulding to obtain neat radii. The essential feature of this is that the intermediate moulding is blown with a length approximately equal to the height of the flat bottle, with a circumference in the body region of -1 to approximately -10%, but in that region of the side walls close to the base from 0 to approximately +10%, in each case based on the circumference of the flat bottle at the corresponding point. In addition, the radius of curvature of the transition from the body wall to the base should be approximately equal to the radius of curvature of the transition of the body wall of the broad side of the flat bottle to its base. The base part corresponding to the pinched end of the parison is pinched during forming. For carrying out the process, an extrusion blow-moulding machine with an end blow mould is used, which consists of two mould halves each of which is composed of two mould parts movable perpendicularly to the mould parting plane, of which the first mould part produces the neck, the narrow side and the base of the flat bottle and the second mould part produces the broad sides of the flat bottle.

Title: Device for unscrewing/tightening wheel nuts/bolts for motor vehicles
Inventor: BOUS GERHARD DIPL ING
IPC: B25B13/06
Filed: 1987-02-20
Abstract: A device for unscrewing/tightening wheel nuts/bolts in motor vehicles is fitted with a screw mechanism (6, 7) for increasing the torque. The screw mechanism spindle (6) is provided with a square end for applying force by means of a ratchet and at the opposite end supported by way of a joint nut (7) in a torque transmission lever (1, 2), which transmits the torque by way of the lever (2), the shaft (1) and the socket wrench (8) to the wheel nut/bolt to be unscrewed. The opposite end of the screw mechanism spindle (6) is axially defined by an articulated support (9) and the support ring (10) and connected to a torque support lever (3, 4, 5), which is supported on the wheel nut/bolt to be unscrewed by means of the tube (4), which encloses the shaft (1) of the torque transmission lever (1, 2), and the lever (3), on a wheel nut/bolt. The reaction torque resulting from the unscrewing or tightening torque is introduced by way of the lever (5) and the tube (4) into the wheel nut/bolt plane and is supported there. This prevents the device from slipping off and the distance between screw mechanism spindle (6) (force introduction plane) and the wheel nut/bolt plane is freely selectable. Inaccessible, jammed wheel nuts/bolts can thus be unscrewed by exerting little force. <IMAGE>

Title: Quick-construction partition wall for fitting up cubicles and partitions in sanitary areas and wet rooms
Inventor: WEDI STEPHAN
IPC: E04B2/74
Filed: 1987-07-10
Abstract: Partition walls used as a rapid-construction system are produced as ready-to-mount elements. Special equipment is necessary for mounting on site. Complex forward planning is required since a quick, flexible reaction to structural inaccuracies is not possible. The object of the invention is to produce a rapid-construction partition wall which permits flexible, repeated erection of a wet-room unit, it being possible for the partitions to be covered with tiles in a professional and aesthetically pleasing manner. The object is achieved according to the invention by a rapid-construction partition wall, in the case of which each load-bearing frame (2) is made up of four U-profile rails (6) which are assembled to form a rectangle and in the case of which the open profile sides are directed towards the interior of the frame, the spacing of the U-legs (10) being dimensioned such that the wall-panel edges can be fitted in properly. The quick-construction partition walls are intended to be installed flexibly and reversibly as tiled partition walls in sanitary areas and wet rooms. <IMAGE>

Patent DE-3733425-A1 (DE)
Title: Racket for lawn tennis and squash
Inventor: SCHMIDT NORBERT
IPC: A63B49/08
Filed: 1987-10-02
Abstract: In order to achieve optimum control of the racket head inclination about the longitudinal axis of the racket, the grip of a tennis or squash racket is widened in the front grip region, in the direction parallel to the racket head plane, so that it exhibits a wide supporting surface, which is as flat as possible, for the index finger at that point, on which surface the index finger rests with a majority of its length transversely to the longitudinal axis of the racket, whereas the grip in the rear region, by contrast, extends only approximately to the conventional width of the standard tennis racket grip and is only about 10% wider than it is high, so that an optimum backhand grip is guaranteed. If an octagonal standard tennis racket grip is provided with this widening at the front, the traditional playing grip and style are ideally combined with the advantage of greater striking precision. A greater torsional stability of the racket is achieved if both the shaft and the throat of the racket are similarly of wider design. The principle of the front widening and the conventional standard dimensioning behind it being retained, other grip variations according to the invention are derived which, in particular, provide for a gradual transition between the front and rear grip width in order to meet the varying requirements of players.
